## Minestarters Atlas summary

GR Silver Mining reported high-grade silver results from step-out drilling at the Plomosas Project. Drill hole SMS25-12 intersected silver mineralization 75m below the existing San Marcial Resource Area, including a high-grade intercept of 0.9m at 956 g/t Ag.

Reasoning: The drill hole SMS25-12 returned a high-grade silver intercept \(232 g/t Ag\) that extends mineralization 75m below the current resource area, representing a successful step-out exploration result.

- Positive factor: High-grade silver intercepts

- Positive factor: Step-out extension of mineralization

- Positive factor: Depth extension below existing resource area

Facts used in scoring: 2

## Classification and evidence

**Bonanza Intercept**

Polarity: positive

Definition: Exceptionally high-grade zone, well above the deposit-type norm.

Why it applies: The 0.9 m interval at 956 g/t Ag is exceptionally high-grade for an epithermal silver deposit.

Evidence · text

> 0.9 m at 956 g/t Ag

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Drilling extended mineralization approximately 75 metres below the current San Marcial Resource Area.

Evidence · text

> extending the mineralization approximately 75 metres \(m\) below the current San Marcial Resource Area

## How Atlas produces this analysis

Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
